BACKGROUND OF THE INVENTION

This invention relates to a new aluminosilicate zeolite comprising a MTT framework designated UZM-53 and its use as a catalyst in hydrocarbon conversion processes. This zeolite is represented by the empirical formula:

M⁺ mRrAl1-xExSiyOz

M⁺ _(m)R_(r)Al_(1-x)E_(x)Si_(y)O_(z)

where M represents sodium, potassium or a combination of sodium and potassium cations, R is the organic structure directing agent or agents derived from reactants R1 and R2 where R1 is diisopropanolamine and R2 is a chelating diamine, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof. UZM-53 has utility in various hydrocarbon conversion reactions such as oligomerization.

Zeolites are crystalline aluminosilicate compositions which are microporous and which are formed from corner sharing AlO₂ and SiO₂ tetrahedra. Numerous zeolites, both naturally occurring and synthetically prepared, are used in various industrial processes. Synthetic zeolites are prepared via hydrothermal synthesis employing suitable sources of Si, Al and structure directing agents such as alkali metals, alkaline earth metals, amines, or organoammonium cations. The structure directing agents reside in the pores of the zeolite and are largely responsible for the particular structure that is ultimately formed. These species balance the framework charge associated with aluminum and can also serve as space fillers. Zeolites are characterized by having pore openings of uniform dimensions, having a significant ion exchange capacity, and being capable of reversibly desorbing an adsorbed phase which is dispersed throughout the internal voids of the crystal without significantly displacing any atoms which make up the permanent zeolite crystal structure. Zeolites can be used as catalysts for hydrocarbon conversion reactions, which can take place on outside surfaces as well as on internal surfaces within the pore.

As used herein, zeolites may be referred to by proper name, such as ZSM-23, or by structure type code, such as MTT. These three letter codes indicate atomic connectivity and hence pore size, shape and connectivity for the various known zeolites. The list of these codes may be found in the Atlas of Zeolite Framework Types, which is maintained by the International Zeolite Association Structure Commission at http://www.iza-structure.org/databases/. The structure type MTT has been described in the literature and is known to contain 1-dimensional 10-ring channels normal to the c axis. Zeolites are distinguished from each other on the basis of their composition, crystal structure and adsorption properties. One method commonly used in the art to distinguish zeolites is x-ray diffraction.

Several related molecular sieves have been disclosed but there are significant differences between those molecular sieves and those of the present invention. Plank, Rosinski, and Rubin describe ZSM-23, the MTT type material, in U.S. Pat. No. 4,076,842 as having a SiO₂/Al₂O₃ ratio of from 40-250 and preferably from 50-220. ZSM-23 is synthesized using a nitrogen-containing organic cation. Valyocsik, describing an improved method of synthesis of ZSM-23 in U.S. Pat. No. 4,490,342 describes ZSM-23 as having a SiO₂/Al₂O₃ ratio of from 40-5000 and preferably from 50-2000. ZSM-23 is synthesized using an organic cation of the formula (CH₃)₃N⁺—R₁—⁺N(CH₃)₃. The present invention involves a SiO₂/Al₂O₃ ratio of less than 60, preferably less than 50 and most preferably less than 44 and is not synthesized using an organic nitrogen-containing cation. Attempts to synthesize ZSM-23 at a SiO₂/Al₂O₃ ratio of less than 50 led to the formation of ZSM-35, a material of FER structure type as disclosed in U.S. Pat. No. 4,016,245.

U.S. Pat. No. 4,837,000 discloses a crystalline silicate, ISI-4, with a specific XRD pattern that is synthesized in the presence of relatively large amounts of ethylene glycol or monoethanolamine.

Parker and Bibby describe the synthesis of KZ-1 in ZEOLITES 1983, 3, 8-11 from reactant compositions comprising pyrrolidine, dimethylamine or 2-aminopropane ranging from a SiO₂/Al₂O₃ ratio of from 55-110 to give a product with a particular XRD pattern and typically having a BET surface area of about 160 m²/g. The present invention is made at lower Si/Al₂ ratios than KZ-1.

Di Renzo and coworkers describe in U.S. Pat. No. 5,314,674 the synthesis of a MTT zeolite with a particular XRD pattern in the absence of any nitrogenous organic agent and in the presence of ethanol. The UZM-53 of the instant invention is synthesized in the presence of two nitrogenous organic agents and in the absence of ethanol.

Zones describes SSZ-32 in U.S. Pat. No. 5,053,373 in the as-synthesized and anhydrous state as having a characteristic XRD pattern, a SiO₂/Al₂O₃ ratio of from 20 to less than 40 and comprising an N-lower alkyl-N′-isopropyl-imidazolium cation such as N,N′-diisopropylimidazolium cation. As prepared, the SiO₂/Al₂O₃ ratio is typically from 25:1 to about 37:1 and can be increased by treating the zeolite with chelating agents or acids to extract aluminum from the zeolite lattice.

Zones and coworkers describe in U.S. Pat. No. 7,390,763 the preparation of SSZ-32X, a MTT zeolite of a certain XRD pattern and a SiO₂/Al₂O₃ ratio of from 20 to less than 40 and preferably from 30 to 35 and comprising, in the as-synthesized and anhydrous form, an N-lower alkyl-N′-isopropyl-imidazolium cation such as N,N′-diisopropylimidazolium cation and an alkylamine such as isobutylamine.

Burton and Zones describe a process for preparing MTT zeolites and MTT zeolite compositions in U.S. Pat. No. 7,157,075 where the MTT zeolites synthesized have a composition in the as-synthesized and anhydrous state with a SiO₂/Al₂O₃ ratio of greater than 15, a ratio of at least one nitrogen-containing organic compound selected from a group including N,N,N′,N′-tetramethylpropanediamine to SiO₂ of from 0.02 to 0.10 and a ratio of alkali metal cation (or alkaline earth cation or mixtures thereof) to SiO₂ of from 0.015 to 0.1.

Nakagawa discloses in U.S. Pat. No. 5,707,601 processes for synthesizing MTT zeolites such as SSZ-32 utilizing small amines such as isobutylamine as the organic structure directing agent. These MTT zeolites have specific XRD patterns and compositions different from those of the instant invention.

Rouleau and coworkers describe in U.S. Pat. No. 6,475,464 an MTT zeolite and process for preparing said zeolite wherein the synthesis is carried out using at least one alkylated polymethylene α-ω diammonium derivative and seeds of a zeolitic material different from the MTT zeolite to be prepared. The present invention does not utilize a diammonium compound, nor are seeds of a framework other than MTT used to crystallize the instant zeolite.

Barri describes in GB2190910 the synthesis of a product they call ZSM-23 from the crystallization of a gel comprising diisopropanolamine and having a SiO₂/Al₂O₃ ratio of greater than 50 and preferably in the range from 60 to 500. The present invention involves a SiO₂/Al₂O₃ ratio of less than 60, preferably less than 50 and most preferably less than 44.

The UZM-53 material may be made from a low flashpoint reaction mixture having a composition expressed in terms of mole ratios of the oxides of:

aM₂O:bMX:cR1:dR2:1−eAl2O₃ :eE₂O₃ :fSiO₂ :gH₂O.

In an embodiment, the mixture that is used to make the UZM-53 contains

20Si:1Al(OH)₃:0.67NaOH:0.67KOH:6.26DIPA:1.266TMPDA:271H₂O

where M represents sodium, potassium or a combination of sodium and potassium cations, “a” has a value from about 0.4 to about 3, MX represents a halide salt of sodium, potassium or a combination of sodium and potassium cations, “b” has a value from 0 to about 12, R1 is diisopropanolamine, “c” has a value of about 8 to about 20, R2 is a chelating diamine, “d” has a value of about 0.0 to about 2, E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, “e” has a value from 0 to about 1.0, “f” has a value from greater than 30 to about 60 and “g” has a value from about 300 to about 2000.

In an embodiment, “d” may be less than 1 or less than 0.50 or less than 0.40. In an embodiment, “f” may be less than about 50. The process may further comprise adding UZM-53 seeds to the reaction mixture. Sources of M include but are not limited to sodium hydroxide, potassium hydroxide, sodium aluminate, potassium aluminate, sodium silicate, and potassium silicate. Sources of MX include sodium chloride, sodium bromide, sodium iodide, potassium chloride, potassium bromide, and potassium iodide. In an embodiment, the source of MX is selected from the group consisting of sodium chloride, potassium chloride and combinations thereof. Sources of R1 can include aqueous solutions, liquid or solid diisopropanolamine or combinations thereof. Solutions of diisopropanolamine are highly preferred. Diisopropanolamine is a low melting (approximately 40° C.) solid which is not easily handled. The IUPAC name is 1-(2-hydroxypropylamino)propan-2-ol. The material either needs to be chipped out of a container or melted and then handled as a liquid, but it readily refreezes unless it is kept at higher than room temperature. However, solutions of DIPA are stable and readily prepared by melting the material and adding water while stirring to make an aqueous solution. The concentration of the R1 solution may be about 50 wt % or may be in the range from about 10 wt % to about 90 wt % or may be in the range from 30 wt % to about 70 wt % or may be in the range from about 40 wt % to about 60 wt %. These solutions may then be easily used in the synthesis. The source of E is selected from the group consisting of alkali borates, boric acid, precipitated gallium oxyhydroxide, gallium sulfate, ferric sulfate, ferric chloride and mixtures thereof. The sources of aluminum include but are not limited to aluminum alkoxides, precipitated aluminas, aluminum metal, aluminum hydroxide, sodium aluminate, potassium aluminate, aluminum salts and alumina sols. Specific examples of aluminum alkoxides include, but are not limited to aluminum sec-butoxide and aluminum ortho isopropoxide. Sources of silica include but are not limited to tetraethylorthosilicate, colloidal silica, fumed silica, precipitated silica and alkali silicates.

In an embodiment, the reaction mixture is a low flammability reaction mixture. The flashpoint of a reaction mixture can be determined by ASTM D93 Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester. In an aspect, a low flammability reaction mixture is one with a flashpoint greater than 50° C. or greater than 60° C. or greater than 75° C. Higher values of the flashpoint by ASTM D93 indicate lower flammability. The reaction mixture is reacted at a temperature of about 150° to about 185° C. for a time of about 1 day to about 3 weeks in a stirred, sealed reaction vessel under autogenous pressure. After crystallization is complete, the solid product is isolated from the heterogeneous mixture by means such as filtration or centrifugation, and then washed with deionized water and dried in air at ambient temperature up to about 100° C. Preferably, the reaction mixture is reacted at a temperature of about 165° to about 175° C. for a time of about 1 day to about 3 weeks. In an embodiment, the reaction mixture is reacted at a temperature of about 165° to about 175° C. for a time of about 1 day to about 1 week.

UZM-53, in the as-synthesized and anhydrous basis, is characterized by the x-ray diffraction pattern, having at least the d-spacings and relative intensities set forth in Table 1 below. Those peaks characteristic of UZM-53 are shown in Table 1. Additional peaks, particularly those of very weak intensity, may also be present. All peaks of medium or higher intensity present in UZM-53 are represented in Table 1. Diffraction patterns herein were obtained using a typical laboratory powder diffractometer, utilizing the K_(α) line of copper; Cu K alpha. From the position of the diffraction peaks represented by the angle 2theta, the characteristic interplanar distances dhkl of the sample can be calculated using the Bragg equation. The intensity is calculated on the basis of a relative intensity scale attributing a value of 100 to the line representing the strongest peak on the X-ray diffraction pattern, and then: weak (w) means less than 15; weak to medium (w-m) means in the range 8 to 35; medium (m) means in the range 15 to 50; medium to strong (m-s) means in the range 35 to 60; strong (s) means in the range 50 to 90; very strong (vs) means more than 80. Intensities may also be shown as inclusive ranges of the above. The X-ray diffraction patterns from which the data (d spacing and intensity) are obtained are characterized by a large number of reflections some of which are broad peaks or peaks which form shoulders on peaks of higher intensity. Some or all of the shoulders may not be resolved. This may be the case for samples of low crystallinity, of particular morphological structures or for samples with crystals which are small enough to cause significant broadening of the X-rays. This can also be the case when the equipment or operating conditions used to produce the diffraction pattern differ significantly from those used in the present case.

In an embodiment, three peaks of strong intensity are present. As will be shown in detail in the examples, the UZM-53 material is thermally stable up to a temperature of at least 600° C. and in another embodiment, up to at least 800° C. Also as shown in the examples, the UZM-53 material may have a micropore volume as a percentage of total pore volume of less than 70% or less than 60% or less than 55% as determined by BET analysis using N₂.

As synthesized, the UZM-53 material will contain some exchangeable or charge balancing cations in its pores.

It may be possible to remove some organic SDAs from the UZM-53 zeolite directly by ion exchange. The UZM-53 zeolite may be modified in many ways to tailor it for use in a particular application. Modifications include calcination, ion-exchange, steaming, various acid extractions, ammonium hexafluorosilicate treatment, or any combination thereof, as outlined for the case of UZM-4M in U.S. Pat. No. 6,776,975 B1 which is incorporated by reference in its entirety. Conditions may be more severe than shown in U.S. Pat. No. 6,776,975.

z″=(a*N+3+4·y′)/2.

In an embodiment, “a′” may vary from about 0.05 to about 0.75 or may vary from about 0.1 to about 0.5. In an embodiment, “y′” may be greater than 12 or greater than 15 or greater than 17 or less than 25 or less than about 22 or less than about 20. In an embodiment, when M1 comprises a combination of sodium and potassium cations, the molar ratio of Na⁺/K⁺ in M1⁺ is in the range 0.10 to 2, and is preferably in the range of about 0.2 to about 0.9. The molar ratio of Na⁺/K⁺ may be in the range from about 0.2 to about 0.75. In the calcined form, UZM-53 displays the XRD pattern shown in Table B. Those peaks characteristic of UZM-53 are shown in Table B. Additional peaks, particularly those of very weak intensity, may also be present. All peaks of medium or higher intensity present in UZM-53 are represented in Table B.

In specifying the proportions of the zeolite starting material or adsorption properties of the zeolite product and the like herein, the “anhydrous state” of the zeolite will be intended unless otherwise stated. The term “anhydrous state” is employed herein to refer to a zeolite substantially devoid of both physically adsorbed and chemically adsorbed water.

The crystalline UZM-53 zeolite of this invention can be used for separating mixtures of molecular species, removing contaminants through ion exchange and catalyzing various hydrocarbon conversion processes. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species. The separation process may comprise contacting at least two components with the UZM-53 zeolite material to generate at least one separated component.

The UZM-53 zeolite of this invention can also be used as a catalyst or catalyst support in various hydrocarbon conversion processes. The catalyst may contain from about 0 wt % or about 10 wt % to about 80 wt % or about 100 wt % of the UZM-53 zeolite. Hydrocarbon conversion processes are well known in the art and include oligomerization, hydrocracking, hydroisomerization, hydrotreating, hydrodenitrogenation, hydrodesulfurization, naphthene ring opening, paraffin isomerization, olefin isomerization, conversion of an aromatic molecule to another aromatic molecule, polyalkylbenzene isomerization, disproportionation of alkylbenzenes, aromatic alkylation, paraffin alkylation, paraffin cracking, naphthene cracking, reforming, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, and dehydration.

Using a UZM-53 catalyst composition which contains a hydrogenation promoter such as platinum or palladium, heavy petroleum residual stocks, cyclic stocks and other hydrocrackable charge stocks can be hydrocracked at temperatures in the range of about 204° C. to about 649° C. (400° to 1200° F.) or about 316° C. to about 510° C. (600° F. and 950° F.). Nickel, cobalt, molybdenum and tungsten are additionally known in the art as hydrogenation promoters. Reaction pressures are in the range of atmospheric to about 24,132 kPa g (3,500 psig), or between about 1379 to about 20,685 kPa g (200 to 3000 psig). Contact times usually correspond to liquid hourly space velocities (LHSV) in the range of about 0.1 hr⁻¹ to 15 hr⁻¹, preferably between about 0.2 and 10 hr-1. Hydrogen circulation rates are in the range of 178 to about 8,888 std. m³/m³ (1,000 to 50,000 standard cubic feet (scf) per barrel of charge), or about 355 to about 5,333 std. m³/m³ (about 2,000 to about 30,000 scf per barrel of charge). Suitable hydrotreating conditions are generally within the broad ranges of hydrocracking conditions set out above.

These same catalysts, i.e. those containing hydrogenation promoters, are also useful in hydroisomerization processes in which feedstocks such as normal paraffins are converted to saturated branched chain isomers. Hydroisomerization is carried out at a temperature of from about 93° C. to about 450° C. (200° F. to 842° F.), preferably about 150° C. to about 300° C. (300° F. to 572° F.) with an LHSV value of from about 0.2 to 1.0. Hydrogen is supplied to the reactor in admixture with the hydrocarbon feedstock in molar proportions (H₂/HC) of between 1 and 5.

Catalytic cracking processes are preferably carried out with the UZM-53 composition using feedstocks such as gas oils, heavy naphthas, deasphalted crude oil residua, etc. with gasoline being the principal desired product. Temperature conditions of about 454° C. to about 593° C. (about 850° F. to about 1100° F.), LHSV values of 0.5 to 10 and pressure conditions of from about 0 to about 344 kPa g (about 0 to 50 psig) are suitable.

Alkylation of aromatics usually involves reacting an aromatic (C₂ to C₁₂), especially benzene, with a monoolefin to produce a linear alkyl substituted aromatic. The process is carried out at an aromatic:olefin (e.g., benzene:olefin) ratio of between 1:1 and 30:1, a olefin LHSV of about 0.3 to about 10 hr⁻¹, a temperature of about 100° to about 250° C. and pressures of about 1379 kPa g to about 6895 kPa g (about 200 to about 1000 psig). Further details on apparatus may be found in U.S. Pat. No. 4,870,222 which is incorporated by reference.

Alkylation of isoparaffins with olefins to produce alkylates suitable as motor fuel components is carried out at temperatures of −30° to 40° C., pressures from about atmospheric to about 6,895 kPa (1,000 psig) and a weight hourly space velocity (WHSV) of 0.1 to about 120. Details on paraffin alkylation may be found in U.S. Pat. No. 5,157,196 and U.S. Pat. No. 5,157,197, which are incorporated by reference.

Isomerization reactions are carried out under conditions identified for the feedstock. Olefins are preferably isomerized at temperatures of about 150° C. to about 500° C. (302° F.-932° F.), while paraffins, naphthenes and alkyl aromatics are isomerized at temperatures of from about 350° C. to about 550° C. (662° F.-1022° F.). Particularly desirable isomerization reactions contemplated herein include the conversion of n-heptane and/or n-octane to isoheptanes, iso-octanes, butane and iso-butane, methylcyclopentane to cyclohexane, meta-xylene and/or ortho-xylene to paraxylene, 1-butene to 2-butene and/or isobutene, n-hexene to iso-hexene, cyclohexene to methylcyclopentene etc.

Catalyst compositions comprising UZM-53 may be particularly useful for the oligomerization of olefins to longer olefins such as gasoline and distillate range olefins. Light olefins such as ethene, propene, butene and pentenes may be oligomerized to gasoline or distillate range olefins. Liquid phase operation is typically preferred. Operating pressures may include between about 2.1 MPa (300 psia) and about 10.5 MPa (1520 psia), but other pressures are contemplated depending on feed and recycle such that liquid phase is maintained. With liquid oligomerate recycle, lower pressures are often possible to maintain liquid phase. Temperature may be in a range between about 100° C. and about 350° C. or may be between about 180° C. and about 300° C. The weight hourly space velocity may be between about 0.5 and about 10 hr⁻¹. Additional conditions for successful operation may be given in U.S. Pat. No. 9,278,893, hereby incorporated by reference.

The proton (H⁺) form of UZM-53 may additionally be characterized by infrared spectroscopy coupled with probe molecules. Ammonia is capable of accessing all acid sites in a MTT zeolite comprising 10-membered ring pores. Adsorbed NH₃ coordinates with both Brönsted and Lewis acid sites. A distinct infrared absorbance band is observed for both types of acid sites. The integrated band area gives a relative measure of total number of acid sites. Discrete desorption experiments provide a relative measure of acid site strength. UZM-53 possesses only small amounts of Lewis acid sites. In an embodiment, the NH₃ Lewis acid value may be less than 0.05 or may be less than 0.04 or may be less than 0.03. UZM-53 possesses large quantities of Brønsted acid sites. In an embodiment, the NH₃ Brønsted value may be greater than 3.00 or may be greater than 4.00 or may be greater than 4.50 or may be greater than 5.00. Collidine adsorption experiments performed in analogous manner yield equivalent information on the external Brönsted acidity of catalyst materials. Collidine (2,4,6-trimethylpyridine) is too large to enter the 10-membered ring of MTT zeolites. UZM-53 possesses only small amounts of external Bronsted acidity. In an embodiment, the Collidine Brønsted value may be less than 0.12 or may be less than 0.10.

The invention will now be further illustrated by the following non-limiting examples.

Example 8

In the present invention, the presence of Brönsted and Lewis acid sites were determined by infrared spectroscopy using the following standard procedures. All procedures started with sample preparation and activation. The samples were ground and pressed into self-supporting pellets. Pretreatment of samples was performed in-situ in UHP 20% O₂/N₂ gas flow at 500° C. for 2 hours to remove water. Gas flow was switched to He and the sample was cooled to room temperature and the hydroxyl spectrum was recorded.

Total acidity determination: The sample was heated to 150° C. and once at this temperature; 1% NH₃ in UHP He was flowed over the sample for 10 minutes followed by equilibration of the sample for an additional 50 minutes. Samples were cooled to room temperature and excess NH₃ was purged in He flow. Desorption experiments were performed by heating the sample in He flow to 150° C. holding at temperature for 1 hour then cooling to room temperature and recording a spectrum. The pretreated spectrum was subtracted from each desorption spectra and the Brönsted and/or Lewis acid site adsorbed absorbance bands integrated to determine the relative total acidity of the materials. The value of the Lewis acid peak divided by the sample mass gives the NH₃ Lewis acid value (area/mg). The value of the Brønsted peak divided by the sample mass gives the NH₃ Brønsted acid value (area/mg).

The external Brönsted acidity determination: The sample is heated to 150° C. and once at temperature He saturated with collidine at 7° C. is flowed over the sample for 10 minutes followed by equilibration of the sample for an additional 50 minutes. Sample is cooled to room temperature and excess collidine is purged with He flow. Desorption experiments are performed by heating the sample in He flow to 150° C. holding at temperature for 1 hour then cooling to room temperature and recording a spectrum. The pretreated spectrum was subtracted from the desorption spectra and Brönsted acid site adsorbed absorbance bands were integrated to determine the Collidine Brønsted value per milligram of the materials (area/mg).

In addition to materials described in the examples, a sample of MTT zeolite from Zeolyst was purchased which had Si/Al=23. All materials were tested in H⁺ form.
